Problems with global-set-key

[JS <d44sf@44ada.com>]

In my .emacs file I have made this:

(global-set-key "\C-z" 'shell)

And it works fine when I restart emacs.




But when I do this:

(global-set-key "\M-a" 'comment-dwim)

I get this error when I restart:




An error has occurred while loading `/home/johs/.emacs':

Symbol's function definition is void: global-set-key 

To ensure normal operation, you should investigate the cause
of the error in your initialization file and remove it.  Start
Emacs with the `--debug-init' option to view a complete error
backtrace
Loading view...done

------------------------

I have then tried to start emacs like this: emacs --debug-init and then I
get this:

Debugger entered--Lisp error: (void-function global-set-key )
  (global-set-key  "á"   (quote comment-dwim))
  eval-buffer(#<buffer  *load*> nil "~/.emacs" nil t)
  load-with-code-conversion("/home/johs/.emacs" "~/.emacs" t t)
  load("~/.emacs" t t)
  #[nil " …—
----------------------------


Why is it not possible to write the second statement?
